Problems solved by technology

[0004] The structure of the above-mentioned composite spinning assembly is relatively simple, but there is a relatively large defect, that is, the filtering method of the two melts inside the upper casing of the assembly is a parallel circular method. Due to the limitation of the cross-sectional area of ​​the inner cavity of the assembly casing, This setting method makes the filtration area of ​​the two melts smaller, the filtration load increases, the pressure of the filter screen increases quickly, and the service life of the components is short. In severe cases, the spinning process is unstable and affects the unit consumption of the melt. Quality of Fiber Products

Embodiment Construction

[0020] The present invention will be further described in detail below by taking the production of island-in-sea polyester composite fibers as an example in conjunction with the accompanying drawings.

[0021] Such as Figure 1 ~ Figure 3 , The assembly as a whole is formed by the upper shell 1 and the lower shell 2 and is fixed with bolts 3 and then enclosed. There are two melt inlets 4 and 5 on the upper side of the upper casing 1, and the PET (polyethylene terephthalate) melt enters the upper casing 1 from the inlet 4, and passes through 3~ Eight connecting pipes 6 enter the annular sand chamber 8; COPET (water-soluble polyester) melt enters the middle position of the upper shell 1 from the inlet 5, and enters the sand tank 9 through the trumpet-shaped connecting pipe 7. The relative positions of the outer wall 8a and the inner wall 8b of the annular sand cavity 8 and the outer wall of the sand tank 9 are concentric circles. The ratio of the radii is: 0.39:1. The ring-sh...

Abstract

This invention discloses a bi-component compound fiber spinning component including an up and down shell, a sand pool, a ring sand cavity, a bearing plate, a series distribution plate, a composite plate and a fiber spraying plate characterizing that the sand pool and the ring sand cavity are coaxial filtering melts of the bi-component separately and serial pin holes are designed on the third distributing plate in the lower shell, pin tubes are mounted in the holes, bottoms of the tubes are set in composite holes matched to duplate which are greatly increase filtration areas of the two melts.

Description

technical field [0001] The invention relates to a spinning assembly for producing composite fibers by melting method, in particular to a spinning assembly for processing two kinds of high polymer melts with different components into composite fibers, which belongs to spinning processing equipment. Background technique [0002] The two-component composite spinning technology is to melt two different polymer melts through a twin-screw composite spinning machine and a special spinning assembly, so that the two components are regularly distributed in the molten state, combined, and then spun through a spinneret to make composite fibers. This technology has two applications: First, the two-component composite fibers produced are of various types, varied, and have their own characteristics, which can combine the advantages of the single-component fibers made of these two components. It greatly expands the performance and application of fibers; secondly, composite spinning technol...
